Authorities raided a San Francisco home in connection with the deadly fireworks explosion that killed seven people in the Yolo County community of Esparto on July 1.

Seven people were "unaccounted for" in Yolo County's town of Esparto after several explosions at a fireworks warehouse resulted in a fire, officials said.

The explosion, which left seven people missing, started a wildfire and forced some cities and counties to cancel or postpone Fourth of July fireworks shows.
